Robust Takagi-Sugeno fuzzy control of a spark ignition engine

Djamel Khiar, Jimmy Lauber, Thierry Floquet, Guillaume Colin, Thierry-Marie Guerra, Yann Chamaillard

This work deals with the nonlinear control of a three cylinders spark ignition (SI) engine using a fuzzy control strategy based on a Takagi-Sugeno (TS) modeling and robust control approach. A physical model of the SI engine is presented and transformed into a TS model. Then, a robust nonlinear…

Développement et évaluation de méthodes d'estimation des masses segmentaires basées sur des données géométriques et sur les forces externes : comparaison de modèles anthropométriques et géométriques, Development and evaluation of methods based on geomatrical data and external forces for estimating segment masses : comparison to anthropometric and geometric models

Julien Leboucher

L’utilisation de paramètres inertiels segmentaires proches de la réalité est primordiale à l’obtention de données cinétiques fiables lors de l’analyse du mouvement humain. Le corps humain est modélisé en un nombre variable de solides, considérés indéformables, dans la grande majorité des études du…, Use of body segment parameters close to reality is of the utmost importance in order to obtain reliable kinetics during human motion analysis. Human body is modeled as a various number of solids in the majority of human movement studies. This research aims at developing and testing two methods for…

Maîtrise de la robustesse de systèmes dynamiques non-linéaires vis-à-vis de paramètres imprécis : application à l'optimisation de suspensions GMP en phase d'avant-projet, Control of the robustness of non-linear dynamic systems subject to inaccuracies : applying to powertrain mounting system optimization during the preliminary project design process

Samuel Boudart

En conception d’avant projet, les impératifs de rapidité et de réduction des coûts sont à l’origine du recours quasi-systématique aux techniques d’optimisation numérique. La conception la plus performante est ici l’objectif principal recherché. Depuis quelques années, les chercheurs et les…, In preliminary projects, numerical optimization techniques allow to obtain efficient solutions rapidly and at lower cost. The aim of such tools is to search and obtain the best design. For a few years, methods of simulation integrating the inaccuracies inherent in the realization of the…

From perception to conflict resolution: priority-managing mechanism for road intersections

Jean-Michel Auberlet, Alexis Champion, René Mandiau, Stéphane Espie, Christophe Kolski

Traffic jams constitute an important problem in the cities. Before improving or modifying the infrastructure and the traffic equipments, it seems necessary to evaluate and to measure their impacts on the traffic system, on the capacity as well as on the safety. The evaluation of the proposed…

A curve-fitting genetic algorithm for styling application

Marc Sevaux, Yves Mineur

The fitting of curves in computer aided geometric design is generally regarded as an optimisation problem. According to the application, conditions to be satisfied can make the problem difficult to solve with classical methods. Stochastic ones, such as genetic algorithms, therefore appear as a…

Needs for methods and models rationalizing work of the actors of an organization implied in an innovation process: basic principles and examples

Christophe Kolski, Emmanuel Adam, Stéphanie Bernonville, René Mandiau

The processes of innovation can be considered before all as business processes; those generally relate to more or less complex organizations. It is possible to understand and improve these processes by exploiting methods and models coming from various fields. Basic principles and examples are…

Recent Advances in Solving the Protein Threading Problem

Rumen Andonov, Guillaume Collet, Jean-François Gibrat, Antoine Marin, Vincent Poirriez, Nicola Yanev

The fold recognition methods are promissing tools for capturing the structure of a protein by its amino acid residues sequence but their use is still restricted by the needs of huge computational resources and suitable efficient algorithms as well. In the recent version of FROST (Fold Recognition…

MEGEVH project: graphical modeling for energy management of hybrid electric vehicles

Alain Bouscayrol, Sebastien Delprat, Daniel Hissel, Rochdi Trigui

The French national MEGEVH project deals with energy management of hybrid electric vehicles (HEV). The objective is to provide general methodologies to model HEV and optimize their energy flows. The project is subdivided in modeling and optimization sub-projects. Graphical modeling has been chosen…
